Someone with this problem?
The rear shocks of my EX, make some grindding noise, the problem is that metal plate in the middle of the two springs hits de body of the shock.
they are not alligned.

That sound is normal.  The spring cup that holds the tender spring and main spring will slide up and down on the shock body.

just make sure they are not wet looking near the bottom mounts.  I had 2 shocks blow out because they backed out a couple threads and the pressure torn them the rest of the way.
